v0.8.0 — World's Best Memory System program

Major feature release implementing the "World's Best Memory System" program — closing the write-rich / close-poor audit diagnosis. All changes additive and backward-compatible (schema additions via CREATE TABLE IF NOT EXISTS; new public API only). Published to PyPI and crates.io.

Ingest integrity

Write-time tool-call artifact sanitizer + corpus repair migration; saturation-gated importance calibration + usage-corrected importance; mega-blob splitting into linked atomic facts.

Autonomous hygiene (close every loop)

Conflicts stamped on recall + auto burn-down; bounded trigger backlog (TTL + over-cap eviction); durable skill outcomes; one run_maintenance_cycle() drives every pass on a host schedule.

Structural query

chain_head() exact chain-head semantics; structural-intent recall hints; list_records surfaced.

Boot sequence

session_digest() one-call briefing; end-of-session auto-capture; trust metadata (age / superseded) on recall hits.

Knowledge graph

Continuous entity backfill + auto_relate co-occurrence edges (graph-lift eval verdict: +2.5% recall on connected data).

Evidence

Runnable, CI-gated harnesses — scaling self-benchmark (precision@scale + latency SLO), graph-lift eval, competitor harness (mem0/Zep/Letta). README claims now cite them.

New schema (additive): namespace_importance_stats, skill_outcomes, artifact_repair_audit. 12 new methods exposed through PyO3. 1591 Rust tests + Python eval suite green; slim (--no-default-features) green.
